Shaft bearing

Abstract

A shaft bearing for supporting a shaft of a motor vehicle includes an inner sleeve, an outer body surrounding the inner sleeve while forming a gap, and an elastomer body elastically connecting the inner sleeve and the outer body. The inner sleeve may have a first rolling surface facing towards the elastomer body and against which a first rolling section of the elastomer body abuts. The outer body may have a second rolling surface facing towards the elastomer body and against which a second rolling section of the elastomer body abuts. The two rolling sections may be connected to each other via a fold having a free length. During movement of the inner sleeve relative to the elastomer body and/or the outer body relative to the inner sleeve, the rolling sections may roll the same distance on the rolling surfaces, so that the free length of the fold remains unchanged.

What is claimed is: 
     
       1. A shaft bearing for supporting a shaft of a motor vehicle, comprising:
 an inner sleeve, 
 an outer body surrounding the inner sleeve while forming a gap, and 
 an elastomer body, which elastically connects the inner sleeve and the outer body, 
 wherein the inner sleeve has a first rolling surface which faces towards the elastomer body and against which a first rolling section of the elastomer body abuts, 
 wherein the outer body has a second rolling surface which faces towards the elastomer body and against which a second rolling section of the elastomer body abuts, 
 wherein the first and second rolling sections are connected to each other via a fold which has a free length, and 
 wherein, during a relative movement of the inner sleeve relative to the outer body and/or of the outer body relative to the inner sleeve, the first and second rolling sections roll over the same distance on the first and second rolling surfaces facing them, so that the free length of the fold remains unchanged. 
 
     
     
       2. The shaft bearing according to  claim 1 , wherein a ratio of an abutting length of the elastomer body to the free length of the fold is 2/1. 
     
     
       3. The shaft bearing according to  claim 1 , wherein the inner sleeve has an appendage forming the first rolling surface. 
     
     
       4. The shaft bearing according to  claim 3 , wherein the appendage is a ring member. 
     
     
       5. The shaft bearing according to  claim 3 , wherein the appendage is connected to the inner sleeve positively, non-positively or by substance-to-substance connection. 
     
     
       6. The shaft bearing according to  claim 1 , wherein the first rolling surface and/or the second rolling surface are contoured. 
     
     
       7. The shaft bearing according to  claim 1 , wherein the inner sleeve and/or the outer body have a single-part or multi-part configuration. 
     
     
       8. The shaft bearing according to  claim 1 , wherein the inner sleeve and/or the outer body are connected to the elastomer body positively, non-positively or by substance-to-substance connection. 
     
     
       9. The shaft bearing according to  claim 1 , wherein the elastomer body has a fastening portion for fastening the elastomer body to the outer body. 
     
     
       10. The shaft bearing according to  claim 9 , wherein the fastening portion is fixed on the outer body via a securing ring.
